It seems slightly incredible that the Mazda MX-5 is now 25 years old. The new fourth generation car was unveiled a couple of weeks ago, so it’s a good time to reappraise the current iteration. Especially as, with all the noise there’s been about the Toyota GT86 and Subaru BRZ bringing back affordable and fun rear-wheel-drive motoring, everyone seems to have forgotten about the poor old MX-5.
